Recommended water type

The following water types are recommended for use in the humidifier:

• Boiled tap water, cooled to room temperature
• Distilled water
• Bottled water (with a low mineral content).

Note: Do not use non-sterile demineralised water for domestic use.

Adding supplemental oxygen

Your Lumis HFT device is designed to be compatible with levels of supplemental oxygen up to 15 L/min.

WARNING

• Always make sure that the device is turned on and airflow generated before the oxygen supply is turned on. Always turn the oxygen supply off before the device is turned off, so that unused oxygen does not accumulate within the device enclosure and create a risk of fire.
• Supplemental oxygen must only be added into your device oxygen inlet at the rear of the device. Adding oxygen elsewhere, ie, into the breathing system via tube, will affect the delivered flow volume, temperature, and humidity.
• Open flames or smoking during oxygen therapy is dangerous and likely to result in fire, facial burns, or death. Do not allow smoking or open flames within 7 ft (2 m) of the device or any oxygen-carrying accessories.
• When intending to smoke, turn the device off, remove the cannula, and leave the room where the cannula or device is located. If unable to leave the room, wait 10 minutes after the device has been turned off before smoking.

CAUTION

Do not connect supplemental oxygen input directly to a medical gas pipeline system, oxygen bottle or other high-pressure oxygen source. A flow regulator must be fitted to ensure the delivered oxygen remains at or below 15 L/min.

For advice on connecting to an oxygen source, contact your homecare provider.

To add supplemental oxygen:

1. Unlock the low flow oxygen input at the rear of the device by pushing down on the locking clip.
2. Insert one end of the oxygen supply tubing into the low flow oxygen input. The tubing will automatically lock into place.

Recommended separation distances between portable and mobile RF communications equipment and the device

The device is intended for use in an environment in which radiated RF disturbances are controlled. The customer or the user of the device can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the device as recommended below, according to the maximum output power of the communications equipment.

Rated maximum output power of transmitter (W)	Separation distance according to frequency of transmitter (m)
	150 kHz to 80 MHz d = 0.35 √P	80 MHz to 800 MHz d = 0.35 √P	800 MHz to 2.5 GHz d = 0.7 √P
0.01	0.035	0.035	0.070
0.1	0.11	0.11	0.22
1 0.35 0.35 0.70
10	1.1	1.1	2.2
100	3.5	3.5	7.0

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in metres (m) can be determined using the equation applicable to the frequency of the transmitter, where P is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer.

Notes:

• At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
